A VISCERA RETAINER

摘要

A retainer (1, 50) to retain the viscera displaced from an internal body area to be accessed for surgery comprises an outer envelope (2) of pliable material with an evacuation port (6). At least two sheets (10, 11, 20) of material are arranged in face to face relation in the envelope (2). The sheets (10, 11, 20) have a forming configuration in which they are relatively free to slide over one another in conforming the envelope (2) to a desired shape and a form retained configuration in which the sheets (10, 11, 20) are restrained from sliding relative to one another on evacuation of the envelope (2). In one case there are sheets (10) of an inelastic material and sheets (11) of an elastic material. Alternatively the sheets (20) may be of the same inelastic material.
